MECHANICAL MOVEMENT.

Specification of Letters Patent No. 26,078, dated November 15, 1859.

To all whom it may concern:

Be it known that I, W1 H. BAKER, of Tamaqua, in the county of Schuylkilland State of Pennsylvania, have invented a new and Improved MechanicalMovement, the same being a means for applying the power of a weight to areciprocating shaft for driving machinery; and I do hereby declare thatthe following is a full, clear, and exact description of the same,reference being had to the annexed drawings, making a part of thisspecification, in which- Figure 1, is a side view of my invention. Fig.2, a vertical section of ditto, taken in the line m, Fig. l. Fig. 3, adetached face View of a portion of ditto.

Similar letters of reference indicate corresponding parts in the severalfigures.

The object of this invention is to obtain a simple mechanism forapplying the power of a weight to a reciprocating driving shaft. Theinvention is more especially designed for operating light machinery suchas churns, washing machines etc. and save the labor required by themanual operation of them.

To enable those skilled in the art to fully understand and construct myinvention, I will proceed to describe it.

A, represents a rectangular frame, which may be constructed in anyproper way to support the working parts. On the upper part of this framea drum B, is placed said drum being fitted loosely on a shaft C, thejournals of which run in suitable bearings a, on the frame. At one endof the drum B, a worm wheel b, is placed, said wheel gearing into ascrew c, on a shaft D, one end of which is fitted in an adjustable orsliding bearing eZ, so that the screw c, may be thrown either in or outof gear with the worm wheel b, when desired. The adjustable bearing (Z,is kept in proper position to retain the screw c, in gear with the wormwheel b, by means of a button e, and catch f; various plans however maybe devised for this purpose. At the end of the shaft D, adjoining theadjustable bearing, a square g, is formed to receive a key L.

On the shaft C, a toothed wheel E, is placed and permanently attached.This wheel E, is connected by a train of multiplying wheels z', with ashaft F, which has a fly wheel Gr, on its outer end. To this outer orface side of the fly wheel Gr, a rim H, is attached eccentrically asshown clearly in Fig. 3. The rim H, which operates as, and .in fact is acam, is fitted between rollers y', j,

attached to a bar or shaft I, which is tted in suitable guides K.

'To the drum B, ropes or chains Z, Z, m, m, are attached in such a waythat the ropes or chains Z, Z, may be wound on the drum in a reversedirection to the ropes or chains m, m, as shown clearly in Fig. 2. Theropes 0r chains pass over pulleys a, placed on suitable shafts, and totheir lower ends a bOX J, is attached, to receive the necessary weightsK.

To the end of the drum B, that is opposite to the toothed wheel E, anannular spring L, is attached. This spring has a tooth or projection 0,attached to its most projecting part as shown clearly in Fig. 1, andsaid tooth is allo-wed in consequence of its shape to pass over the armsof the wheel E, when the drum is turned to wind the ropes or chains Z,Z, m, m, thereon, but the tooth catches against one of the arms of wheelE, if the drum be turned in the opposite direction.

The operation is as follows: The shaft D,

is elevated so that the screw c, will be thrown in gear with the wormwheel I), the shaft being retained by the button e. The key h, is thenapplied to the shaft D, and the latter turned, motion being therebycommunicated to the drum B, so that the ropes or chains Z, m, will bewound thereon and the box J, elevated. When the box is fully elevatedthe shaft D, is depressed so that the screw c, will be thrown out ofgear with the worm wheel Z), and the weights K, then descend rotatingthe drum B, and the latter through the medium of the tooth o, on thespring L, giving motion `to the wheel E, train of wheels z', and shaftF, the cam `I-I, on the fly wheel Gr, imparting a reciprocating motionto the bar or shaft I, to which the machinery to be operated isconnected. More or less weights may be used in the box J, according tothe power required.

By having the ropes or chains Z, m, attached to the drum B, as shown,the drum is relieved of friction in turning on shaft C, as the ropes orchains are wound on it, and the journals of shaft C, are also relievedof friction, when the dveice is in operation.

The invention has been practically tested and answers an excellentpurpose for operating churns, washing meachines, and other lightmachinery. Its adoption will save Weight 0r Weights attached to it asshown, in connection With the toothed spring L, toothed Wheel E, trainof Wheels z', fly Wheel Gr, and cam H, fitted between the frictionrollers y', of the shaft I, the Whole being combined and arranged tooperate as and for the purpose set forth.
